BitMine Immersion Technologies just added another 27,084 ETH to its balance sheet, paying roughly $43 million for the haul. The purchase brings the company’s total Ethereum holdings north of 5.7 million tokens, representing approximately 4.7% of the circulating supply.
From Bitcoin miner to Ethereum whale
BitMine, trading under the ticker BMNR, has undergone a dramatic identity shift. The company pivoted from its origins as a Bitcoin mining operation into what is now essentially an Ethereum treasury vehicle, guided by chairman Tom Lee, the Fundstrat founder who has spent years as one of Wall Street’s most vocal crypto bulls.
BMNR’s total crypto and cash holdings are now estimated at around $9.8 billion. This latest $43 million purchase is just the most recent in a string of acquisitions throughout 2026. The firm has executed multiple large ETH buys this year, including a single tranche of 126,971 ETH for approximately $214 million.
Lee has indicated that the accumulation will continue through the rest of 2026. The strategic target is clear: reach 5% of Ethereum’s total supply by year-end. At 4.7%, that finish line is getting close.
The playbook behind the buying
BMNR has been timing its purchases around market dips, essentially buying weakness rather than chasing momentum. Lee has attributed recent ETH price softness to quarter-end portfolio adjustments, the kind of seasonal rebalancing that temporarily pushes prices lower without reflecting any fundamental change.
The funding mechanism is worth understanding. BMNR isn’t just selling equity to buy tokens. The strategy is partially bankrolled by staking rewards, meaning the Ethereum the company already holds generates yield that helps fund additional purchases. On top of that, the company has filed for preferred stock yielding 9.5%, creating another capital channel specifically designed to fuel further accumulation.
Lee has acknowledged that the strategy involves riding through unrealized losses during price corrections.
Why Ethereum, and why now
Lee has been vocal about his belief that Ethereum is entering a supercycle, one driven by real-world asset tokenization migrating onto the network and the growing intersection between blockchain infrastructure and AI demand.
What this means for investors
There’s also the question of what BMNR’s preferred stock offering means for retail investors in the company itself. A 9.5% yield is attractive, but it’s attractive precisely because it carries risk. That yield is ultimately backed by a volatile asset, and the company’s ability to sustain it depends on Ethereum maintaining or growing in value.
